TO ALL WHOM ITMAY CONCERN:

Be it known that I, J. L. BEERS, of McAlisterville, in the county ofJuniata, and State of Pennsylvania, have invented a new and improvedFeed-Mechanism for Sawing Machines; and I do. hereby declare that thefollowing 'is a full, clear, and exact description thereof, which willenable those skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecicati'omin Which- Figure 1 is a side view of my invention. Y

Figure 2, aplan or top view of the same.

Similar letters of reference indicate corresponding parts. I g

This invention relates to a new and useful improvement in thefeed-mechanismof sawingmachines, and it consists in the employment oftwo pawls and gearing arranged in such amanner that a continuous feed isobtained, and one which may be regulated to suit the speed of the cut ofthe saw as may bedesired.

A represents a framing constructed in any proper mannen to suit theworking parts, and B represents a pitman which drives a reciprocatingsaw, said pitman being operated by a crank-wheel, a, at one end of adrivingshaft, This shaft C has a pinion, D, upon it, which gears into awheel, E, the latter being double the size of the pinion D. The wheel Ehas a pitman, F, attached to it, and the upper end of said` pitman isprovided' with a piu, which works in a slot, c, made longitudinally inan arm, G, which works on a pivot bolt, d, in the framing A. l 4This armG is of T shape, as shown clearly in fig. 1, and to each end of itsinner part e there is attached a pawl, H. These pawls both engage with aratchet, I, on a shaft, J, from which shaft motion is communicated' tothe log carriage by the usual rack and pinion or by any 'other suitablemeans. The Pitman F isl connected by a rod, K, with a lever, L, theupper `end of which passes through a slot,f, in a horizontal plate, M,on the framing A, the plate M being notched at one side of the slotf tohold the lever L at any desired point. Fromr the above description itwill be seen that the pawls H H act alternately upon the ratchet I, onepawl moving- 4the ratchet 'while the other is being drawn back, andvz'ce versa. Thus a. continuous feed movement is obtained,

the log or article to be sawed being fed to the saw while the lattermoves both up and down. The feed movement of the log, however, is slowerthan usual in consequence of the wheel E being double the size of thepinion D, and the speed of the feed movement may be varied, as desired,by adjusting the pitman F nearer to or furtherl from the outer end ofthe arm G, a greater or less vibratory movement being given the arm G bythis means so that the speed of the feed may always bemade commensurate'with the speed of the cut of the saw.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- Controlling the feed-motion by means of the lever L,rod K, pitman F, pin b, notched plate M, T shaped slotted arm G, pawls HH, arranged and operating substantially, as described for the purposespecified.
